CalSTRS and APG have set up a consortium to invest in North American energy infrastructure, it is understood.
The asset manager owned by Dutch pension fund ABP would not 鈥渃onfirm nor deny鈥 media reports that it is investing alongside The California State Teachers鈥 Retirement System.
CalSTRS confirmed to IP Real Estate that it had joined a 鈥渓arge institutional investor鈥 in the venture.
The consortium is open to additional commitments from third-party institutional investors.
The two investors will each invest $250m (鈧230m) in the consortium, which will be run by investment manager Argo Infrastructure Partners.
CalSTRS said the alliance is an opportunity to build a 鈥渕ore diverse portfolio of investments in North America than they would have otherwise been able to make on their own鈥.
ABP has a 鈧30bn stake in energy and energy infrastructure, alongside 鈧1bn invested in sustainable energy, including onshore windfarms.
Spokesman Harmen Geers recently said ABP wanted to double its share in renewable energy to 鈧2bn.
鈥淔inding the right investments is not easy, as the investment must be at least 鈧100m, and our investment criteria prevent us from owning more than 50% of any project,鈥 Geers .
APG last year invested in European energy, putting 鈧250m into a European hydropower venture with alternative investments manager, Aquila Capital.
The new consortium will invest in core operating energy assets, including pipelines, storage facilities and power utilities.
CalSTRS said it will target facilities with existing cash flows that will need ongoing maintenance and future expansion capital.
Former JP Morgan Chase infrastructure chief investment officer, Jason Zibarras, recently created Argo, which will invest in low-risk assets in Canada and the US.
CalSTRS established its infrastructure portfolio in 2010 to diversify away from equities following the financial crisis. The pension fund, as of the end of last year, had $1.3bn committed to infrastructure globally.
